iOS 7’s most important updates have already been rolled out, but the improvements aren’t stopping at versions 7.0.2 and 7.0.3. Today, Apple released iOS 7.0.4 for the iPhone, iPad, and iPod touch in an over-the-air update. It’s a minor release, but one that could be really appreciated by a subset of users.

iOS 7.0.4 was released solely to improve the performance of FaceTime, Apple’s video conferencing service. With all that talking and front-facing video recording going on, FaceTime was encountering some errors with crashing and other annoying bugs. Most of those should be be squashed as of today.

A quick run through Apple’s support forums shows that “FaceTime crashing” has been a complaint that’s popped up now and then, but it’s far from a widespread issue (as we saw with iOS 7’s messaging problems earlier this year). Now that Apple has fixed the biggest issues with iOS, it seems like the company is working its way down the priority list and is deploying isolated fixes and some fine-tuning, as we saw here.

Today also saw the release of iOS 6.1.5 for the fourth generation iPod touch. This model was released just about a year ago, but is not compatible with iOS 7. This release shows Apple’s continued support for the product despite the fact that it unfortunately (or fortunately, depending on who you ask) missed out on the explosion of neon colors and transparencies that is iOS 7.

The previous update to iOS 7, version 7.0.3, was the biggest release to the mobile OS since it first landed. This update brought the ability to turn off animations during app opening and closing, and fixed the quite serious problems people were having with the Messages app.

iOS 7.0.4 is available for download now. It’s just 17MB and should take about 10 minutes to install.
